1 Corinthians 2:6

Wisdom] Christianity has a wisdom of its own. While it is centred in a Person, it is capable of being expressed in the terms of philosophy, and is in harmony with all that is best in human reasoning and speculation.

Perfect] St. Paul divides Christians into two classes, the beginners and the advanced. The former must be taught the simple truths of the gospel and grounded in its facts: the latter are able to receive teaching regarding God's plan in redemption and His purpose as it is revealed in Christ and illustrated in the history of the world. 'Perfect' means 'mature,' 'full-grown,' and is applied to Christians of ripe experience and character. It is often used in this sense in the Epistle to the Hebrews: cp. Ephesians 4:13; Colossians 1:28; Hebrews 2:10; Hebrews 5:9; Hebrews 5:14; Hebrews 9:9; Hebrews 10:1, etc.

The princes of this world] 'The men of light and leading' (Dods). They showed utter ignorance of God's mind: cp. 1 Corinthians 2:8.
